I came across a bootleg from 1976, at Buffalo, NY. I believe it was in the spring, maybe in May of that year. The entire show was clear perfection, but the Help/Slip/Franklin's Tower is the best I have ever heard. They played these songs for the first time that year at the Great American Music Hall. That version is also incredible. My band loves to play that song; even though it's relatively basic, you can jam for hours and hours...
